Installation steps

  1. Connect PSU 24pin to ADT-Link, PSU PCIe 8pin and 8pin to GPU, Switch Jumper on ADT-Link R43SG SW1 to 2 (Power Supply always on, to detect GPU)
  2. Check device manager if GPU found (if not test M.2 with a drive, etc.)
  3. Install latest Nvidia driver
  4. Restart (triggering error43 is mandatory, yellow triangle in device manager)
  5. Run nvidia-error43-fixer

@4567-dll, Great job 👏 I have been waiting to see m.2 performance of rtx 3080. Could you please add some game performance with and without rtx/dlls by confirming that you have 32gbps 4x3.0 pciex bandwidth

@fotoroman, thank you. no, my 4k city in Anno 1800 is burning :- ) you can compare the results to 32Gbps-TB3 builds and see it's significantly faster https://egpu.io/best-external-graphics-card-builds/

@4567-dll, so you are happy with your egpu game performance Smile yes I know that post but that comparison was done with 1080ti, can we say that m.2 egpu performance of rtx3080  does not experiencing more than 20 percent performance lost?

my current notebook has gtx1660ti as dgpu, my concern is getting the same performance with my dgpu because of bandwidth limit, if I use rtx 3080 egpu

@fotoroman,

No you can't say that. But you can compare the Timespy gpu.io builds benchmarks, and 3080 Desktop benchmarks, it averages about 21%. Further than that, I'd stop wasting time and have fun. It will blow 1660ti out of the water. This build is 100 EUR, if you don't like it just sell the GPU.

100% GPU Desktop performance
~78% GPU Notebook M.2 performance
~63% GPU Notebook TB3 performance (~20% less than M.2 performance)

So I have 4 lane 32Gb TB3. Are we 100% sure I should be looking at ~20% boost just by swapping my interface to an M.2 4 lane 32Gb NVMe slot? We aren't talking 2 lane TB3 vs 4 lane M.2 here possibly?

@flows, there are some benchmarks that do better with PCIe 3.0 x1 compared to Thunderbolt 3.
https://egpu.io/forums/thunderbolt-enclosures/a-call-for-measurements-isolating-the-thunderbolt-effect/paged/17/#post-14987

These were done more than 3 years ago though. Maybe we need updates with Ice Lake and Tiger Lake and newer GPUs.

 

Mac mini (2018), Mac Pro (Early 2008), MacBook Pro (Retina, 15-inch, Mid 2015), GA-Z170X-Gaming 7, Sapphire Pulse Radeon RX 580 8GB GDDR5, Sonnet Echo Express III-D, Trebleet Thunderbolt 3 to NVMe M.2 case
